UPASITA® was created by Ajinomoto Pharmaceuticals Co., Ltd. (currently EA Phama Co., Ltd.) and developed by SANWA KAGAKU for the treatment of secondary hyperparathyroidism under a licensing agreement with EA Pharma. UPASITA® acts on calcium sensing receptor in the parathyroid and suppresses excessive secretions of parathyroid hormones (PTH). UPASITA® is administered by intravenous injection to dialysis patients through dialysis circuit by physicians or medical staffs upon completion of dialysis and such administration is expected to reduce the burden of patients with many oral medications whose drinking water volume is severely restricted.

Regarding provision of medical and drug information, SANWA KAGAKU entered into a co-promotion agreement in Japan with Kissei Pharmaceutical Co., Ltd. (Head Office: Matsumoto, Nagano; Chairman and CEO: Mutsuo Kanzawa ; "Kissei"). SANWA KAGAKU will handle the production, marketing, and distribution of the Product while SANWA KAGAKU and Kissei collaboratively promote it to medical institutions in the field in accordance with the agreement. Through the co-promotion activity in the field, SANWA KAGAKU and Kissei will contribute to the treatment of dialysis patients suffering from secondary hyperparathyroidism.

About secondary hyperparathyroidism (SHPT)
SHPT is one of the complications that occur as chronic kidney disease (chronic kidney failure) progresses and is a pathological condition where excessive PTH is secreted by the parathyroid gland. It has been reported that excessive secretion of parathyroid hormone promotes efflux of phosphorus and calcium from the bone into the blood, thereby increasing the risk of developing bone fractures and arteriosclerosis due to calcification of the cardiovascular system and affecting the vital prognosis.
